AJ, the only food I can think of that I've never seen anyone here say is bad for them is rice. Since you obviously can't eat just rice, you'll just have to use trial and error, I guess.
To start with, I'd stay away from spicy and fatty foods, also dairy products and very high fiber foods like beans and raw fruits and veggies. Those seem to be the things that bother most people. Try introducing one or two foods and see what bothers you and what doesn't.
Protein takes longer to digest, but is very high in food value. Carbs are the easiest to digest, but too many carbs can cause problems. I'd just try a little of things, trying to keep the diet balanced.
Moderate to severe left-sided UC diagnosed 2001.
Current meds are Colazal, Azathioprine and Remicade. Completely off steroids for more than a year now! In remission since April, 2006. Remicade has been my wonder drug.
Now tapering Azathioprine, please pray for me.
